Summary:Due to increased costs and risk of supply chain uncertainty, rare-earth free traction motors are gaining significant interest in the automotive industry. The wound field synchronous motor offers a rare-earth free alternative to the permanent magnet synchronous motor and also shows additional benefits such as high-power factor, lower iron loss at high speeds and improved safety under fault conditions. In this paper a methodology is developed for design and optimization of such a motor for high volume automotive traction applications. The optimization process consists of two steps. The first step employs an analytical model coupled with a high population genetic algorithm to search in a large design space. The second step uses the Surrogate Finite Element (SFE) method for fast design optimization using the output of the first step as the initial population. A detailed cost and efficiency trade-off is used to select the motor for the final design.
